What do Unequal Length Headers Sound Like on a V6 Honda Odyssey?

- Опубликовано: 24 мар 2022
- I made my Honda J series GROWL with this UEL header setup! I'm sure you haven't heard a v6 with a setup like this before, let alone a freaking minivan. This ain't your mother's regular Honda Odyssey muffler delete!
If you're curious, this van specifically has a Honda J35A4 motor in it. It's currently mated to the BYBA 5 speed automatic transmission, for which I'm building a controller that will allow me to manually change gears.

That’s definitely a unique sound. I can’t even actually describe the sound..
Growly single turbo RB / old six cylinder
🥵🥵🥵🥵
4.0 straight six in a jeep
Sounds like an old lemans race car
Reminds me of an older flat 4 imo
couldn't have said it better, never heard something like this before... much less a minivan
Can't believe I'm saying this but it seriously sounds like a Porsche 6 cylinder from the 90's. Bravo, dude.
Your comment made me look for videos of that... And holy crap, you're right 😳
Yeah I was gonna say the same thing I wanted to look at the comments if anyone thought the same
Immediately came to mind. Sounds horrid lol
I’m loving minivans more and more, I’ve always loved what the boostedboiz have done with mini vans and now I coin this channel and I’m absolutely loving it. Keep it up man, this is fun to watch.
First off, vans are dope. Thanks for keeping the van love alive!
Secondly, sounds amazing! Great job
It sounds kind of similar to GMs 3.8 V6 sent in Monte carlos, Grand Prix, regals etc. Factory they came with unequal length headers because the engine is transversal and instead of a typical exhaust running under the engine there’s an over pipe going from the front manifolds to the rear which cause an odd sounding V6. At idle and very low RPMs (especially with a cam) they sound like a V8 due to the rumble and slight rasp it gives off. That’s until you give it revs and the rasp gets worse and worse 😂
GM sound of power. Same tone, but louder or quieter depending on rpm.
Lol literally just said the same thing, sounds like my buick. The crossover on the 3800s really does add alot of resonance and unwanted rasp.
Muricans and their hate for rasp, never ceases to amaze me
@@davidaugustofc2574 Americans love rasp, just step outside and hear all the raspy Chargers buzzing past.
Once you finish this video, check out this newer video where I take the Odyssey out and get some great sound clips of it driving!

not gonna lie it sounds kinda good. I've always loved v6´s. amazing video
ok lol i always wondered why some v6s sounded like VQs and some sound like clapped out grand caravans, and i never considered headers as a possible cause, and i think that's the difference lol
Subbed for the 2 stroke content and confidence. Way more than I have.
dude ive seen your tiktoks and wanted to hear unequal headers on something that wasnt a 4cyl thank you for this vid
You got me subscribed with "I refuse to believe minivans aren't cool"
Thanks! I've been finding what a uel v6 sounds like, appreciated
You look a fair amount like the lead singer from Title Fight. Just had to say that. Not only that, but I like your content. Definitely a new subscriber :D
I 100% planned on skipping to the end to hear the end result, but damn bro. I actually enjoyed listening to you speak. Your enthusiasm is contagious. F it lol Oh, and I'm glad I did watch til the end, bc I'm floored by how damn well that Hodyessy sounds. (Have you ever seen Bo Burnham?) Btw I'm in central pa too.
Thanks, that really means a lot to me- Of course I've seen Bo!
Dude good job! Very nice project! I am a new followers!
Ya know i was all sorts of stoked when back in like 2010 right around the 5th gen camaro comi g out, we stated seeing V6 engines making 300+ Hp. Finally it didnt feel like settling when you bought a V6 Camaro or mustang. I even bought a 2012 Awd Charger with the 3.6. It was a great car that madebdecent power, especially moving that barge around. The only problem was the sound, in factory trim it sounded like a vacuum cleaner, and try as i might i could not find an exhaust that would produce a decent sound. You sir have succeeded where i failed, that sounded magnificent. I mean that not just for a V6 but it sounds great in general. Well done
*_Aweseome build man!_*
the j35 is already the best sounding v6 by far, this takes it to the next level.
I think it sounded really good before the j pipe, and with the jpipe installed you didn’t do any pulls so I couldn’t compare it to the revved up video before
Great point! I'll finally be able to do some pulls once I finish the transmission controller.
That sounds amazing with UEL on it... I'm literally putting UEL on any and all vehicles I ever own haha I love when cars have a rasp in the exhaust it makes the car sound far more aggressive. Imagine a gtr rolls up to the meet with the most aggressive sounds UEL on it making it sound like some kind of insane track toy lol
Sounds pretty awesome. Good work
Thanks! I'm pretty excited to hear how it'll actually sound under load!
Definitely has that old school american pushrod V6 sound. I bet this would sound sick on an accord as well.
Sounds nice. I'd be interested in seeing whether you could do a 6-into-1 on this thing.
Now you need some aggressive cams. This sounds amazing!
had a na miata that me and a local exhaust shot made a unequal length header for , used a magnaflow muffler on it to retain a nice deep sound and even without a resonator it wasnt raspy at all , magnaflow is by far the best as ive heard in many other cars , but definately put a good ressy on that asap lol ,
I'm working on a follow-up right now! I put a resonator on a while ago now and it's SOOOOO much better
Scott did my truck exhaust. Good guy.
I think the J pipe reduced the rasp, but i like your thinking in terms of flow. If I'm correct unequal length pipes create a broader torque curve, while equal length create more peak hp/tq. Keep rocking the "cool bus". 😎
It's hard to tell for sure with the rasp considering I also switched to that high flow cat. I'll never stop rocking the cool bus, don't you worry!
Try a decent resonator to give it some depth and then after that whack in a flowmaster super 44 or similar muffler. That particular muffler sounds great on a subaru with uel headers. I have this setup on my klde V6 2.5 FWD and it sounds good, even with equal length headers. I might give this uel j pipe business a go on my car. Sounds really unique man.
Thanks! A little while after this I added a 12" long Vibrant resonator, and it really cut down on the rasp. If you do wind up trying it out for yourself, I highly suggest frequently checking clearance with your subframe, mine's cutting it pretty close 😅
Yes, I did wonder what uneven length headers sound like on a V6! It's literally the reason I came here!
Sounds like the v6s from the 90s 4Runners very cool sound
Great video
it sounds so unique. It has a hint of v8 v6 and i4
thats actually pretty cool you were able to do that. But I have to say, it kinda just sounds like it has a bad exhaust leak lol
Sounds like old inline 6, kinda cool
Great mate!
Cool work man, myself I preferred it equal length. Sounded kinda like a Nissan VQ engine. Now I’m not sure what to compare it to haha
As long as you like it, that’s what matters
Thanks! I definitely preferred the tone when it was equal length, and wasn't a huge fan of the rasp introduced from the high flow cat. However, I just added a resonator and I think it really improved the tonality, I'm hoping I can get it in a video soon!
@@tnast hey I dig this video I’m trying to get an idea of what my Nissan 350z HR engine would sound like with unequal length headers if I custom built them for it. I’m trying to get a “subi rumble” on a VQ
VQ sounds so good though !!! I love that trumpet like little growl it makes.
I don’t know anybody who actually likes the sound of a VQ, such a horrible sounding engine
How to pronounce puch: (pu-GGGGG)
But i love that you got one, given it's european and a piece of history.
I have a 2007 Odyssey and I have to try this.
Been really wanting to buy or make a uel header for my integra might actually do it now.
Wow that's crazy that I stumbled across this video. I did the EXACT same thing to a v6 honda accord, although it was a lot shittier than your welds. It was made from flex pipe from the auto parts store, which I'm pretty sure you're not even supposed to be able to weld it, but I did anyway. And used JB Weld to seal all the leaks. It made it sound like a BMW inline six.
I've actually seen the videos of that on your channel, and they're definitely part of why I did this! I heard the underlying tones and decided "that'll do" lol
You've created your signature sound; nice one 👍
Really loved the enthusiasm you put into this video, however, in my knowledge, that is not a J-pipe, a J-pipe is a type of resonator. I would call that a merge pipe since it merges two frequencies toghether. Once again, great video tho!
Thanks! Turns out J-Pipe usually refers to a style of resonator as you mentioned, but Honda's literature also refers to this piece as a J-Pipe... Gotta love the confusion!
Sounds sorta like the 3800 V6 from my old Buick Lacrosse
Sounds like a Buick 3800, which makes since since they are basically UEL from factory.
4.3 Chevy motor. That's what this reminds me of. Maybe GM uses special headers to get their V6s to sound deeper.
for second I thought someone cranked up my Grand Prix with the 3.8 engine and has unequal setup from factory
That shit sounds nice asf 🔥. You know anybody that make uel headers for j series?
Thanks! I think P2R makes one, iirc "big tube" is part of the name.
You try to add a flowmaster hp2 i have one on my 05 straight pipe Odyssey it will give a very deep sound idle like a corvette
I’d love to see this car so when you said central pa I got excited i live down in red lion pa! I got a 3000gt that I wanna do uel headers
You'd better be going to Carlisle imports this month! I'd love to see your 3000gt, there's hardly enough of them around.
I have an 02 odyssey and before seeing this video I was trying to see how I could do this! Can you tell me the factory flange diameter so I buy the right pipes for my DIY? Thank you for an awesome video!
What I did here was I already had the headers and their J pipe, and just reused their flanges. HOWEVER, I soon found out they were incredibly warped, so I switched over to a set of v-bands, which have held up great so far.
Vibrant resonator
I think it sounds awesome and almost v8 like
Doing this to a Nissan Quest with a VQ would be interesting
please drop the carbon dash kit PLEASEEE i need to spend my money on that
Sounds like an inline 6 from a 1950s truck in a good way.
Honda and Puch are the best no doubt
I love it
I dig it
Im building mine now i love my 2nd gen
I want to if if that same set up you have on your 3.5 Honda Odyssey van will fit my 3.0 Honda Accord and if so how much would you charge me to have the same set but with the catback system I already have on the car...
In theory it'll fit, aside from the different length between the front and rear cylinder banks. If I had a J30 to mock up with, and a better workspace, I'd take you up on the offer, but unfortunately I just don't have the facilities to do that kind of fabrication without having the car on hand.
Equal length with an x-pipe and duals also sounds bitchin. Proof: ruclips.net/video/9OGpFTLDm_U/видео.html&ab_channel=Sy1v
Hey new to the Honda community is this swap possible for a FWD 97 crv
Coolest odyssy is kinda difficult now with the plaidyssy
Sounds like a GM 3800… and those guys do everything in there power to make it not sounds like a 3800 😂😂
I think you can kill the battery if you weld on the car with it connected. I had the same issue and always disconnected prior to welding now.
Very interesting... I personally couldn't tell you if it was a defective Motorola radio or the welding that did it
It's not the battey that you can kill its the more sensitive electronics such as your ecu that can get damaged. it's unlikely to actually happen in reality though it's still worth taking precautions
Bring the content back bro manual swap the van hmu for info
sounds like a vr6 from vw!
Turned it into an Pontiac Grand am lol
I want to do this to the subaru h6.
Are you using a wide band for each bank?
Just one for both banks
gives me classic wanna be muscle car (I6) vibes
Are you the dude who has a 3d printed “sequential” shifter?
Yes I am- I've got a few other videos on here about it!
Could I pay you to do this to my 07 6-6 accord? Similar engine 😅
It wouldn't be cheap, but I'd definitely consider doing it. Biggest challenge is not having the car on hand to test fit everything as I go.
Close to the ol 4.3 vortec, uneaven length on them from the factory
Sounds like a 3800 for sure, went out of my way to change that as much as possible. Sorry man, wrong direction with sound. Good experiment though
Unequal is one thing but you still need to tune how unequal it is. Try to get the exhaust pulses just right.
WHUY
Sounds exactly like a 3800, and the funny thing is people put equal length headers on those.
Sounds old school
starts at 3:50
Sounds like a 3.8 series 2
This is basically how Tacoma's are
Sounds like gm 4.3 vortec
You have a manual ODYSSEY?
Well, manual-ish 😅
@@tnast It sounds like a manual. Great work man
I got the third gen
The deeper growl you're getting with the new J pipe is literally just an audible representation of inefficiencies in your exhaust setup. The perfect exhaust setup in theory would be one where each primary pipe from the header to the collector is exactly the same length, and every pipe would join to a 6-1 collector where the cylinders are firing in a rotary pattern. A setup like that has a high pitched overtone because you're hearing the fundamental frequency of the exhaust pulses coming through uninterrupted. Any lower pitched frequencies that come through in the form of a growl or pulsing or whatever else it may be is a result of pulses colliding in the pipe as a result of the runner lengths being unequal and cancelling out the higher frequency and replacing it with some harmonic of that fundamental. If you want the most power possible from your headers, you need that equal length J pipe, even if it has a 180 degree bend. Most headers you get online will say they're "equal length" but they usually have a decent difference in the actual primary runner length. The only company that comes to mind that's actually done a proper equal length header setup for a v6 is SG Motorsport with their VQ35 headers. Once you've got some actual equal length headers, you can do a y pipe to join the two headers to one, and if the secondaries for your y pipe are also equal length, you can get away with the same diameter of pipe you used after your primary collector. For this engine, 3 inch is so overkill it's not even funny, maybe 2 and 1/4 inch would get a little more power.
Is that how v8s have that low rumble growl at idle? Thye just run unequal headers to 3" or bigger collectors and then straight pipe that out or just stop at the collecters and run open headers?
@@White_Night_Demon Nah, only cross-plane crankshaft v8s sound like that because the left and right banks don't fire in even alternating pulses. In a 4 stroke engine where you have 720 degrees, two rotations, per cycle, you have to have each cylinder firing within that 720 degrees. For a v8, that means having a cylinder firing every 90 degrees. In a flat-plane v8, like in a Ferrari, each bank fires in an alternating sequence, as in L-R-L-R-L-R-L-R. That gives you 180 degrees between cylinders on the left bank firing and 180 degrees between cylinders on the right bank firing. Because the pulses are even and the crank separation is constant, you get that smooth, high-pitched exhaust note. On a cross-plane v8, you have two cylinders on each bank firing consecutively per sequence, as in R-L-R-L-L-R-L-R. That means that on the left bank you have 180-90-180-270 degrees of separation, and on the right bank you have 180-270-180-90 degrees of separation. Because there's one header for each bank, even with equal length headers, you still have exhaust pulses reaching the collector in uneven pulses. That gives you the uneven v8 rumble you hear from American or BMW/Mercedes v8's.
Interesting notes on this:
- If you've got a cross-plane v8, you can still make it sound like a flat-plane v8 by putting 180 degree headers on it. These are headers like on the GT40 where two cylinders from the left bank cross over to the right bank, and two from the right bank cross over to the left bank.
- The Ferrari F136 v8 was used in Ferrari's, Maserati's, the Alfa Romeo 8C and the Gillet Vertigo. In the Ferrari's, like the F430 and 458, it uses a flat-plane crank, whereas in the other applications, the put a cross-plane crank in it. Listen to the difference between a Ferrari F430 and a Maserati GranTurismo MC Stradale, similar engine, different crank configuration and completely different sound.
- The BMW S63 v8 in the F10 and F90 M5 uses a hot V with unequal length 180 degree headers (look at a photo to see what I mean). If you listen to the 550i compared to the M5, you can pretty clearly hear that the 550 sounds like a traditional V8, and the M5 sounds really weird.
@@ScottGroome So what would unequal length long tube headers do to a crossplane v8 if it's already got uneven pulses make that low rumble? Make it rumble even more? Like window/house shaking throaty rumble level like on some cars I've noticed idling at stop lights or just idling near your house?
I dont know... SLq5UTJBhK0 and y2fREOoFtGU sound pretty close....the former being the 550i and the latter being the f90.... What would make it sound even better is if it had a blow off valve for that shhh sound or one of those blown superchargers with the nice gilmer belt whine....mmmm.......or both if you can somehow fit both in...
Fix it . Sounds like a 3.5 eco boost . Equal length is way to go or 6 to one header
It sounds like a 1jz vvti on low revs lmaooo
sounds like a 1jz vvti at low rpm
It kinda sounds like a 1JZ tbh
"I refuse to accept that minivans aren't cool."
As you should, minivans are practical vehicles for people who aren't scared to be themselves. Cowards pick SUVs. =P
Well I know what the "stock" unequal lenght setup sounds like on a 3.7 grand cherokee.... videos deep in my channel
sounds like a GM v6
I also hate people callin my odyssey lame. I made it one of the bigger attention grabbers
Lmfao you made it sound like a 3800 and that's not a good thing
3800s sound dang good with the right exhaust. Its kinda funny how well the note fits the car
just a cheap version of p2r longtubebes 😂😂😂😂
YOURE A FUCKING LEGENDE
